MACHINE FOR ORNAMENTING LEATHER.

SPECIFICATION forming part of Letters Patent No. 375,105, dated December 20,1887,

Application filed June 8, 1887.

To aZZ whom, it may concern.-

Be it known that I, EDWIN B. STIMPsoN, of Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Machines for Ornamenting Leather, of which the following is a specifica- My invention relates to a machine for ornamenting leather by impressing the leather to form recesses on one side and corresponding raised ribs or projections on the other side, the recesses being subsequently filled with a plastic filling to maintainthe full projection or prominence of the ribs or raised portions.

In my improved machine are comprised, in combination with a sliding mandrel and an oppositely-arranged bed, dies which are .carried, respectively, by the mandrel and bed,

and one of which has surface portions of different configuration, and one of which isrnovable laterally to bring theportions of different configuration on one die into and out of coincidence with the other die, and the lower die is also movable to expose it for the reception of material to be operated on; and I furthermore employ stops for limiting the lateral movement of the die or dies and insure their correct position for successive operations. I

also provide a connection through which the mandrel is operated from a lever or other device, and which is adjustable in length, so as to vary the range of movement of the mandrel to suit dies of different thickness.

The invention consists in novel combinations of parts in a machine, as hereinabove referred to, and hereinafter particularly described, and pointed out in the claims.

In the accompanying drawings, Figure 1 rep resents'a sectional elevation of a machine embodying my invention. Fig. 2 is a sectional elevation in a plane at right angles to Fig. 1. Fig. 3 is a horizontal section upon about the plane indicated by the dotted'line w m, Fig. 1. Fig. 4 is a section, corresponding to Fig. 1, of a portion of the mandrel, the supporting-bed, and the dies, illustrating a slight modification of my invention. Fig. 5 is a front elevation of the parts shown in Fig. 4. Fig. 6 is a plan of the bed and the die supported thereon corresponding to the modified construction shown in Figs. 4 and 5. Fig. 7 is a gage or pattern Serial No. 240,573. (No model.)

which may be employed for cutting or trimming the ornamented leather. Fig. 8 is a sectional view showing the method of using such gage, and Fig. 9 is a view of a toe-cap.

Similar letters of reference designate corresponding parts in all the figures.

A designates a suitable frame, wherein is guided a mandrel, B, here shown as lockedin the frame to prevent its turning by a feather or spline, b, entering the groove 1). This mandrel B may be operated by means of a lever, O, fulcrumed at c, and a linker connection, 0, which is composed of two end portions or eyes connected by a portion having right and left screw-threads, and which may be turned to increase or diminish the length of the conface portion, d, while the die D has a grooved or fluted portion, (1 corresponding to the portion (I of the die D. One of the two dies D D is movable laterally to bring either the surface d or d of the die D into and out of coincidence with the surface (I of the die D, so that after theleather has been operated upon by the portion d d of the two dies to impress in it ribs or ridges the portion d may be brought into coincidence with the portion (1 of the lower die, D, and by again depressing the mandrel apiece of covering fabric-such as paper or cloth-may be cemented and pressed firmly upon the leather. In this example of the invention the lower die, D, is alone movable laterally,and it is also movable to a further extent than described, to afterward expose the die D so that leather may he placed upon it, and so that after leather is pressed by the portions (1' d the impressed leather may be exposed to enable filling material to be placed in the recesses or depressions before the covering fabric is cemented thereon. In the operation of these parts the die D, having a piece of leather upon it, is brought to the position IOC formed with grooves or depressions.

shown in Fig. 1, and such position is definitely fixed by a spring, (1, which is secured to the die D and has a prong or projection entering a notch or recess, 02*, in the bed A, as shown best in Fig. 2, and also in Fig. 3. The lower die, D, is locked in position,with its portion (1 immediately opposite the portion d of the upper die, and by depressing the mandrel B the leather, by the action of the dies D D, is The die D is then moved laterally outward to an extent limited by a projection, 61", on the die striking against the inner edge of the bed A, and the filling material,which may consist of cords, but which preferably consists of plastic material-such as gum, dextrine, or paperpulp-is placed in the grooves or depressionsin the leather. The die D is then slid inward to a greater extent than before,and until its inner edge strikes against the press frame A, as shown at d by dotted lines, and in this position the plain surface d of the die D is in coincidence with thesurface d ofthc die D, and by depressing the mandrel B a piece of covering fabric-such as paper or cloth-is secured by cement and pressure upon the leather and over the filling material. By means of atemplet, S, which may have a ridge or shoulder, s, to fit against the outermost rib or ridge in the leather, and which is applied to the leather, as shown in Fig. 8, a gage is afforded for trimming off the edge of the leather.

In the example of my invention shown in Figs. 4, 5, and 6 the die D, which has the fluted or grooved portion d, as before described, is supported upon the bed A,- but the bed is pivoted at the end d so that it,may be swung outward laterally, as shown by dotted lines in Fig. 6, and it may be retained in definite position by a spring'catch, d entering a notch, d", in the free end of the bed, and by a stop pin, secured in the bed. The upper die, D, in this example of the invention has the portions (1 d of different configuration, as before described, and slides in a channel or dovetailed recess, 6, in the stock plate or piece E, secured to the mandrel B. It is provided with a handle, 6, whereby it may be slid laterally, and its movement toward the left hand of Fig. 4 is arrested by an upturned finger, c", which strikes against the edge of the plate E, and its movement toward the right hand of Fig. 4 may be limited by the said finger e striking against the frame A. The lateral movement of the die D in this example of the invention provides for bringing either of the portions d or (1 into coincidence with the portion (1 of the lower die, D, and the swinging movement of said lower die provides for exposing such die to receive the ma terial upon it, and to permit of the filling of the recesses or depressions formed by the parts (I d of the dies. It will be obvious that .although I have shown in this example of my invention dies for producing substantially parallel ribs or ridges, the dies may be formed to impress the leather in any other oranmental shapes.

What I claim as my invention, and desire to secure by Letters Patent, is

1. In the herein-described machine for ornamenting leather, the combination, with a sliding mandrel and an oppositely arranged 'bed, of dies carried, respectively, by the mandrel and bed, and one having surface portions of different configuration, and one of which is movable laterally to bring the portions of different configuration on one die into and out of coincidence with the other die, and the lower die being also movable to expose it for the reception of material to be operated on, and stops for limiting the lateral movement of the die or dies and insuring their correct position for successive operations, substantially as herein described.

2. In the herein-described machine for ornamenting leather, the combination, with aslid ing mandrel and an oppositelyarranged bed, of dies carried, respectively, by the mandrel and bed, and one having surface portions of different configuration, and one of which is movable laterally to bring the portions of different configuration on one die into and out of coincidence with the other die, stops for limiting such lateral movement, anda connection, adjustable as to length, through which the mandrel is operated,substantially as herein described.
